To all 'whom tmay concern:

Be it known that I, HUBER'rfF. KnAN'rz, a citizen of the United States, residing at Brooklyn, in the countyof Kings, city and State of New York, have invented certain new and useful Improvements in Meter- Panels, of which the following is a clear, full, and exact description.

This invention relates to an improvement in meter ancls.

The oblect of the invention is to provide a meter panel which is simple in'construction, positive inaction, and in which a greater range of operation may be obtained than in those now in use.

A further object is to provide improved 'means for contacting any selected meter bar while by the same movement contacting a contact member of opposite polarity.

A further and more detailedobject is to provide two branch circuit terminals, to provide supporting means whereby one of said terminals may betadjustedrelatively to the other so as to stand adjacent a selected meter bar, and to provide means whereby both terminals may thereafter be moved into con tacting relation with their respective adjacent bars.

A further object is to rovide meansforpreventingmovement of either of the terminal or contact members except when the adjustable terminal is in the correct position for engaging a selected meter bar.

A further object Vis-to provide supporting means for the terminal or contact 'members adapted to' support the adjustable terminal in such relation to a 'gang of meter bars that said adjustable terminal may be. readily moved transversely across and -above the gangof meterbars tofits desired position,

and in fulll and clear view of the operator.A

A further object` is to .so arrange the' parts that a plurality' of branch line terminals may supported at opposite sides ofthe gangof meterbars, and the adjustable terminals" atone `sideA be sta gered with respect. to those at the other si Q So that eachmayhave unobstructed access to all of the meter bars in. a minimum -of length of meter bar. f

more or-less specific than those referr'rd toV Other objects and aims of theinveiitiom above, will be in part obvious and 1 n part pointedeout in the course of the followmgdescriptionof the elements, combinations, ar-

rangements of parts and applications of 'form of switch.

pinciples, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as-a part of this specification, and 1n which I have shown merely a p1e ferred form of embodiment of the inven- .tion:-

A meter 9 l(only one being illustrated 1n the drawings) is connected to the neutral contact 4 by a wire 10. A wire :12. leads from 'the meter -to aterminal 11and a wire 100 14 leads from the meter to a meter bar 13.. The usual fuse I5 is interposed in the meter circuit between the bar 8 and the terminal 11..

It will be understood'of course that there rate fuse 15 for-eachterminal- 11;

neutral, bar 6 is connected with a pair ofA neutral busl bars 19*L which are spaced apart in substantially parallel relation. Iln thc space between these neutral bus bars is arranged any number of meter bus bars 13 parallel with each other and with the neutral Ams bars all being insulated from each other by suitable insulating spacers asibest seen The switchet 19 include an adjustable'or selector contact 20 and a non-adjustable contact 21. The selectorcontacts 20 are carried upon a rod 22 which is slidably mounted in a support 23 so that said selector contacts may b e readily slid back and forth transversely of th'e gang of meter bars 13into a position above any selected one of said meter bars. -The contacts 21 are arranged" to cooperate with the neutral `bus bars 19.

The neutral bus bar 19 at one side of the 'gang o f meter bars is adapted to be enga ed by the contacts 21'of the.'switches 19 atj 0H position the teeth 25'stand within a -lpngitudinal groove 27 formed in the slide rod in communication with all of the transverse grooves. While the teeth 25are in the 'groove 27 the slide rod may be-nioved back and forth at will but a partial rotation.

bar-19a performs the same function for the switchesat the opposite side of the gang.

All of the switches 19 are identical in construction and operation and in each the slide rod 22 is adapted to he rotated-within the support 23 for swinging the contacts 2O and 21 into and out of contacting position. The

hrde 20 may` be translated intoi position :i ve any desired meter bar and then rotated in that particular posit-ion. while the blade 21 rotates with the blade 2() but without translation.

-The blade 21' is fixed to a. sleeve'30 which is rotatably mounted within a se aratesupport 32 and through -which Athe s ide rod 22 l. 1s freely longitudinally movable: The `pin i or screw 33'is carried by the sleeve 30 'and' engages l within a groove 2S formed'longitudinally in-the slide rod 22 so thatsaid sleeve at all times rotates with the slide rod.

Suitable insulating. material 31 isl interposed to prevent owiof current between the sleeveand the slide rod. y

-The function 'of each switch 19 is to.closc the branch circuit which it represents be tween one of the neutral bus bars 19*l and a selected one of themeter'bars 13 in :order that any 'oneiof the meters can be thrown' in the-branch circuit controlled hy that switch.

In order to' prevent sldihg movement of the sl-ide rod 22 except whuthe contact 20 thereof is 4 iri the ottposition, a series of transverse grooves-24 is formed in the sur?.

face of the slide rod'and ythe teeth 25'of Za4 vlocking block 26' carried by the support 23 engage-within sud'grooves at all times except when the contact 20 is m' the `full off` position. When thccontact 20 is in the full respectively.

which is coincident, with the of the slide rod to move the contact 20 toward the on position will cause the tecth 25 to enter the transverse grooves and ini-- mediately prevent further longitudinal movement. y y

As best seen in Figs. 5 and 6 the transverse grooves extend throughout Iapproximately one-quarter of the circumferential surface of the slide rod, thus permittin up# t 'e `that the contacts 2O and 21 will at all times move together into on or olf positions and that both are in the olf osition during any selective adjustment o the contact The supports 23 and 32 are provided with fuse clips 29 and 32"L by means of which suitable fuses may connect. said supports with the branchv circuit contacts 18 and 17 Fi 7- illustrates .a modified form. of switc In this instance an arm 34 ismounted lfor mechanism' which embodies Somer -what the same principle as above described.

In this instance the meter bus-bars 49 are arran ed one over the other and over tlie neutral ar 50 vertically. To change the position of the switch blades 51, the pin 45 will be pulled outwardl until the blades 51 clear the bar; the dis 46 is then rotated until the blades 51 aline with the desired bai' and then the pin 45 Ireleased to allow the spring to force the blades into contact with tlie bar'.

Figs. 10 and l1 illustrate a form of switch consisting of a carrier 52 rotatably supported in a standard 53. In this form the meter bus-bars 54 and neutral bus-bar 55 are ar ranged in parallel, but the switch 4blades 56 are arranged in a radial formation, eac biis-bar 54 having its arm switchblades.Y To throw in the various bus-bars the carrier 52 will berotated until the proper set of blades 56 comes in contact with the desired bar. The carrier 52 supports a bushing 57 of in sulating material upon which are mounted the neutral switch blades and 59, the said blades being electrically connected by 4a sleeve 60. The blades 59 consist of disks bus-bars, arranged (Fig.11) which permanently contact with the terminal contact 61, the blades 58 being in the form of a, spider having as many arms as'tliere are blades 56.

The bus-bars are provided with contact surfaces 62, between recesses 63, which are for the purpose of allowing a blade to break contact with a bar before the next blade comes into contact.

As manyV construction without departin scope of the invention as define in the following claims, it is intended that all matter contained in the above descriptionI or s hown in the accompanyin drawings, shall be interpreted as illustrative only and not. in a limiting sense. i
